This invention relates to methods of making metal bars and fence posts constructed therefrom. a

The object of this invention isto provide [if a new process of continuously rolled metal templates the formation of spacedstuds projecting outwardly from said flanges particularly adapted for use in securing a wire fence, or the like, when lengths of these bars are used as fence posts.

Other objects will be more fully set forth in the following specification and illustrated in the accompanying drawings in which Fig. 1 is a front elevation o a post embodyin my invention, a portion of the fence being illustrated as attached thereto.

process partially illustrated in Figs.- 9 and 10.

Fig. 12 is a horizontal section of the bar illustrated in Fig. 11'.

Like numerals refer to like elements throughout the drawings in which 10 indicates generally a portion of a continuously rolled steel bar illustrated in crosssection in Fig. 8, for example. I

In the form illustrated in Figs. 1 to 8, the bar is constructed of polygon-like or tubularlike construction with a front side or face 10-a, side walls or faces 10-?) and a rear open. side across which partially extend opposed flanges 10-0. Projecting outwardly at the rear edges are the fastening studs 10-d.

In Fig. -1 I have illustrated a drive type fence post formed of such a bar, it being my intent *to roll these bars of suitable or desired lengths and thereafter to cut them to proper length for fence posts. The post may be readily driven into the ground in the usual manner by the use of sledges or driving instruments and a woven wire fence, for example, generallyindicated by numeral 20, care flat surface at the back, repsented by the flanges 10-0, after which tying members 21 are utilized to secure the strands of wire to the rear face of the post in any number of suitable ways, as indicated in Fig. 2, for example, the tying members being preferably provided with engaging looped end. 21-a, the other end being bent, after attachment, to engaging position.

The studs 10-d co-act with the tying members 21 to prevent sagging or slipping of the strands of wire of the fence.

The tubular-like or polygonal-like construction, while permitting driving of a post into the ground, encompasses or surrounds a substantial amount of dirt or material and thereby presents a substantial resistance to movementof the 0st in any lateral direction in contradistinction to present day fence posts. In other words, there is an earth-locking action with the polygonal-like post of I what might be termed an enclosed column of earth or ground material, so that there is more area of the post i'nterposing a resistance to lateral movement of the post in proportion j to the weight thereof thanin any prior type of construction. j

At the same time a relatively high resistance to torsion is presented for the weight of metal utilized. Also a substantial flat surface is presented for contact with the fence, which renders it relatively easy to stretch the fence before fastening thereof to the post, while the fastening studs lO-d permit a nonsa attachment.

n Figs. 4 to 8 I have illustrated various steps of one process of manufacturing or continuously rolling the bars from which the fence posts are made.

In Fig. 4 is illustrated the first strand pass where the blank A, which, for example, may be a heated steel rail, is passed betweenopposed forming rolls 30, 31.

In Fig. 5 opposed rolls 32, 33 effect a sec- 20 nd strand pass of'blank A, which is shown in section in the entire series of drawings illustrating the forming operation.

In Fig. 6 rolls 34, 35 effect a third strand ass. 86 In Fi 7 rolls 36, 37 effect a leader pass or fourt forming operation.

In Fig. operation. 1 In the first four operations, illustrated in 80 partially to completed condition or shape in what I' term a developed condition, i. e., in a flattened form, while in the fifth and last operation the sides are not only shaped to the final dimension, but are bent or formed in final or finished relation with the flanges 10-0 inturned, as illustrated, and the studs 10-d are out-turned and finally dimensioned.

In the first operation, illustrated in Fig. 4, the flanges 10-0 are partially formed and in succeeding operations are brought to or toward final dimension. Similarly, the metal, which is ultimately utilized for the studs 10-d, is formed ina flange until the fourth opera tion, illustrated in Fig. 7, when the studs are formed by recesses 36-a in the upper roll 36, the final operation of Fig. 8, embracing the studs to their final form.

The third operation, illustrated in Fig. 6, is unique as being, what is termed in the art, an overfill in which the flanges A from which the studs are later formed, are moved inwardly of their position in the second operation of Fig. and formed in the grooves 34-a of the upper roll 34, while metal is extruded outwardly from. the partially formed flange A from which flanges -0 are ultimately formed. This overfill operation has hitherto been considered either impractical or not feasible in rolling operationsof this character, but I have found it desirable in the method described.

In Figs. 11 and 12 I have illustrated a.

slightly modified form of a continuously rolled ar useful for certain purposes, which rolls 38, 39 effect the finishing Figs. 4 to 7, for example, the blank is brought in lieu of the studs IO-d are provided outwardl extending flanges 10-9 shown, in the embo iment illustrate as substantially co-, planar with flangeslO-a.

In Figs- 9 and lO I have illustrated two variant steps of the process illustrated in Figs. 4 to 8 desirable to form thebar of Figs. 11 and 12. In Fig. 9 is illustrated a variant fourth pass of the blank in which upwardly extending flanges at the outer edge are left upon the blank, While in Fig. 10 they are rolled to final shape and dimension in final or finishing operation.

2. A process of rolling polygon-like metal bars consisting in rolling the blank partially to completed condition in developed form with a pair of angularly disposed flanges at each side thereof, forming studs of one of each pair of flanges and passing said blank between rolls constructed to shape the same in polygon-like form with an'open side, with the other flanges projecting partially across said side and with said studs projecting outwardly from said bar.

A. process of rolling polygon-like metal bars consisting in rolling ablank partially to completed condition with flanged portions at the sides thereof, formingstuds ofa'flange at each side thereof and passing'said partial- 'partially across ly completed blank between rolls constructed to shape it in polygon-like form with an open side and inturning' other flanges partially across said open side.

4. A process of rollingtubular-like metal bars consisting in rolling a blank partially to completed condition in developed form and angularly disposed flanges above and below said blank at one side thereof, and thereafter passing said blank between rolls constructed to shape the same inrtubular-like form with an open side, and with oneof said flanges projecting partially thereacross and the other of said flanges projecting outwardly from said bar. 1

5. A process of rolling tubular-like metal bars consisting in rolling a blank partially to completed condition in developed form with angularly disposed flanges above and below said blank at each side thereof, and thereafter passing said blank between rolls constructed to shape the same in tubular-like form with an open side with one of the flanges at each side thereof projecting inwardly partially across said opening and the other flanges projecting outwardly from said bar.

6. The process of rolling tubular-like metal bars consisting in rolling a blank to partially completed condition with flanged portions at the sides thereof, thereafter passing said blank between complementary rolls, one concaved and the other convened, in such wise as to bring said blank to tubular condition with an open side and with said flanges directed inwardly partially across said open side.

7 A process of rolling tubular-like metal bars consisting in rolling a blank to partially completed condition in developed form and forming angularly disposed flanges above and below said blank at the sides thereof, and thereafter passing said blank between complementary rolls, one of'which is concaved and the other convexed, to shape said blank in tubular-like form with an open side and with flanges extendin partially across said open side and other anges projecting outwardly from said first named flanges.

8. A process of rolling tubular-like metal bars consisting in rolling the blank partially to completed condition in developed form with enlarged portions at one side thereof, thereafter passing said blank between rolls constructed to shift one of said portions inwardly of said bar, leaving a portion projecting outwardly thereof, subsequently rolling said outwardly projection portion and said shifted portion to form flanges thereof, and

finally bending said bar to tubular shape, ecting outwardly with one of said flanges pro thereof and the other projecting inwardly thereof.

9. A process of rolling tubular metal bars consisting in rolling the blank partially to completed condition in developed form with enlarged portions at each side thereof, subsequently passing said blank between rolls constructed to shift one "of said portions at each side of said bar inwardly, leaving outwardly projecting flanges, then rolling said blank to form oppositely directed flanges of said projecting portions and said shifted portions at each side of said blank, and finally bending said blank to completed tubular shape with an open side and with flanges projecting outwardly and the closed flanges projecting inwardly partially across said open side.

In witness whereof, I hereunto subscribe my name this 10th day of February, 1931.
